Conversion of Polypropylene Into Liquid Fuel Using Bleaching Earth as A Catalyst
This study aims to determine the effect of the addition of BE (Bleaching Earth) catalyst on the amount of liquid fraction produced by polypropylene (PP) plastic and to know the concentration of gasoline and diesel fraction from the PP pyrolysis. This study used the pyrolysis method (heating in the absence of oxygen) with a mass variation of BE catalyst which is 2.5 grams, 5 grams, 7.5 grams and without catalyst. Liquid fractions from the pyrolysis of PP plastic were analyzed using GCMS (Gas Chromatrographic Mass Spectrometry). In this study the amount of liquid fraction produced in each mass variation of BE catalyst which is 2.5 g, 5 g, 7.5 g and without catalyst was 39.75%, 32.88%, 32%, and 14% respectively. The results of GCMS analysis show almost the same compound data in each sample which has carbon elements in the range C8 to C17. Selective BE (Bleaching Earth) catalysts for gasoline and diesel fractions wherein the concentration of gasoline fraction for each variation of BE 2.5 g catalyst mass, 5 g, 7.5 g and without catalyst were 43.78%, 41.86%, 77, 05%, and 67.4%, while the diesel fraction is 55.56%, 58.14%, 22.95% and 32.59%.
